New Revision: 2431

URL: http://svn.digium.com/view/zaptel?view=rev&rev=2431
Log:
Support OSS output again.  Of course, we still can't (currently) output non-combined streams.
It'll still stereorize (it's a real word now) the combined stream.
I'm not sure how it should work with multi-channel streams.
